ohm's law question

stevdart, I found the information online, thanks.  Hopefully I'll understand it.  I guess some of the people on here have an engineering or electronics background, but I have none of either.  So reading things that are written by advanced engineers is a real nightmare for me.  I know because my father is one of them.  They use technical terms that a newbie does not understand, so really, I feel like a need a translator.  I was hoping to get a very brief answer in plain English that anyone could understand.

And Kartuneman, thanks for your reply I think.  I didn't really understand what you said.  In my last post I stated that I might get a JL Audio 12W7 sub which I think is one 3-ohm voice coil and takes 750 watts RMS.  I asked what amp someone would recommend that would put out the right amount of power for this sub.  I think that JL Audio says that 1,000 watts RMS is too much and 500 is too little.

Plan, Research, Do

That's just plain wrong.  Ohms are ohms and low is not better than high or vice versa.  Lower ohm load on an amp will cause it to push more current and result in more power output, but at the cost of SQ, noise, heat generation, power load on your system, etc.  Too low an ohm load will blow fuses and can fry your amp.  Higher ohm loads sound much cleaner and allow your amp to function with less power draw and less heat and more safely.  Matching the ohms load of your loudspeakers to the best operating characteristics of your amp is the "better" thing to do.

NOPE, even if i could monoout anything, joining the output of two channels into one, sometimes affectionately referred to as bridging,   has no affect on impedance!!! i repeat, no affect

that said, the impedance presented to the amp does greatly affect output performance, but has no change on impedance. of course you must disregard all of this when wiring up the flux capacitor
